Richard, I'm not exactly following you, do you need a replacement for your current Princess stove's butane canister holder, or do you want to find a way to connect a different type of canister to the brass hose connector shown in photo #3? If the former, you could replace the portable butane stove for around $35. If the latter, that seems like serious plumbing to me... Not my wheelhouse, sorry.
